More facets of hard disk recovery (SA1000, RD53) and emulation

by djg＠pdp8online.com

I have made a SA1000 adapter board for my MFM reader emulator. I did a small run which seems to work so if you are interested email me to get in on the next order. Prices may get a little better if I get enough orders. http://www.pdp8online.com/mfm/ http://www.pdp8online.com/mfm/sa1000/sa1000_usage.shtml I have used it for reading Shugart SA1004 and Quantum Q2040 drives. Another has used it to replace drive in a TRS-80 Model II 8 Meg drive unit. Some other items that may be of interest: Dealing with stuck head problem with Quantum Q2040 drives http://www.pdp8online.com/q2040/q2040.shtml Using a DAC to pull the head servo to recover otherwise unreadable data >from DEC RD53 drive. Also procedure tried for Q2040 but data had been erased so not successful. http://www.pdp8online.com/mfm/head_servo/

tape transport drive belts

by binarydinosaurs＠gmail.com

Evening folks, I?m bringing a Sharp MZ80B back to life and have so far fixed a horizontal collapse problem on the video board meaning I can see what it?s prompting for at boot. I remember when I first got this machine back in 2003-ish I dismantled it and discovered some of the tape transport had melted and gummed up the automatic head mechanism. Fast forward* 15 years and I have the transport in bits again on the bench and I can see that one belt has melted and another is on the way to collapse. Did we ever find a reasonable source of replacement belts? I know a couple of collector friends with 3D printers have printed replacements but this is new tech and I need old tech :) Cheers! *sorry, pun intended -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest private home computer collection? t: @binarydinosaurs f: facebook.com/binarydinosaurs w: www.binarydinosaurs.co.uk

DEC TKZ10 Tapes

by bill.gunshannon＠hotmail.com

Does anyone have any DC6525 tape cartridges they would be willing to part with? One of the Expansion boxes on my VAX has a TKZ10 but none of the older QIC tapes I have can handle the format from this drive. bill

Tandy RS DWP-220 printer equivalent?

by seefriek＠gmail.com

My google-fu is failing me; forgive me. Is the Tandy DWP-220 daisy-wheel printer a rebrand/OEM of someone else? In particular, can I find ribbons and font wheels under another manufacturer? KJ
